### XSLT 3.0 Draft – Saxon 9.6

Thursday, October 2nd, 2014

I saw a tweet by Michael Kay announcing:

and,

Saxon 9.6 released!

Now that is a great Thursday!

PS: Deadline for comments on the working draft is 26 November 2014.

### Sharing key indexes

Wednesday, June 4th, 2014

Sharing key indexes by Michael Kay.

From the post:

For ever and a day, Saxon has tried to ensure that when several transformations are run using the same stylesheet and the same source document(s), any indexes built for those documents are reused across transformations. This has always required some careful juggling of Java weak references to ensure that the indexes are dropped from memory as soon as either the executable stylesheet or the source document are no longer needed.

I’ve now spotted a flaw in this design. It wasn’t reported by a user, and it didn’t arise from a test case, it simply occurred to me as a theoretical possibility, and I have now written a test case that shows it actually happens. The flaw is this: if the definition of the key includes a reference to a global variable or a stylesheet parameter, then the content of the index depends on the values of global variables, and these are potentially different in different transformations using the same stylesheet.

Michael discovers a very obscure bug entirely on his own and yet resolves to fix it.

That is so unusual that I thought it merited mentioning.

It should give you great confidence in Saxon.

How that impacts your confidence on other software I cannot say.

### 7 First Public Working Drafts of XQuery and XPath 3.1

Friday, April 25th, 2014

7 First Public Working Drafts of XQuery and XPath 3.1

From the post:

Today the XML Query Working Group and the XSLT Working Group have published seven First Public Working Drafts, four of which are jointly developed and three are from the XQuery Working Group.

The joint documents are:

• XML Path Language (XPath) 3.1. XPath is a powerful expression language that allows the processing of values conforming to the data model defined in the XQuery and XPath Data Model. The main features of XPath 3.1 are maps and arrays.
• XPath and XQuery Functions and Operators 3.1. This specification defines a library of functions available for use in XPath, XQuery, XSLT and other languages.
• XQuery and XPath Data Model 3.1. This specification defines the data model on which all operations of XPath 3.1, XQuery 3.1, and XSLT 3.1 operate.
• XSLT and XQuery Serialization 3.1. This document defines serialization of an instance of the XQuery and XPath Data model Data Model into a sequence of octets, such as into XML, text, HTML, JSON.

The three XML Query Working Group documents are:

• XQuery 3.1 Requirements and Use Cases, which describes the reasons for producing XQuery 3.1, and gives examples.
• XQuery 3.1: An XML Query Language. XQuery is a versatile query and application development language, capable of processing the information content of diverse data sources including structured and semi-structured documents, relational databases and tree-bases databases. The XQuery language is designed to support powerful optimizations and pre-compilation leading to very efficient searches over large amounts of data, including over so-called XML-native databases that read and write XML but have an efficient internal storage. The 3.1 version adds support for features such as arrays and maps primarily to facilitate processing of JSON and other structures.
• XQueryX 3.1, which defines an XML syntax for XQuery 3.1.

To show you how far behind I am on my reading, I haven’t even ordered Michael Kay‘s XSLT 3.0 and XPath 3.0 book and the W3C is already working on 3.1 for both. 😉

I am hopeful that Michael will duplicate his success with XSLT 2.0 and XPath 2.0. This time though, I am going to get the Kindle edition. 😉

### Balisage Papers Due 18 April 2014

Tuesday, March 18th, 2014

Unlike the rolling dates for Obamacare, Balisage Papers are due 18 April 2014. (That’s this year for health care wonks.)

From the website:

Balisage is an annual conference devoted to the theory and practice of descriptive markup and related technologies for structuring and managing information.

Are you interested in open information, reusable documents, and vendor and application independence? Then you need descriptive markup, and Balisage is the conference you should attend. Balisage brings together document architects, librarians, archivists, computer scientists, XML wizards, XSLT and XQuery programmers, implementers of XSLT and XQuery engines and other markup-related software, Topic-Map enthusiasts, semantic-Web evangelists, standards developers, academics, industrial researchers, government and NGO staff, industrial developers, practitioners, consultants, and the world’s greatest concentration of markup theorists. Some participants are busy designing replacements for XML while other still use SGML (and know why they do). Discussion is open, candid, and unashamedly technical. Content-free marketing spiels are unwelcome and ineffective.

I can summarize that for you:

There are conferences on the latest IT buzz.

There are conferences on last year’s IT buzz.

Then there are conferences on information as power, which decides who will sup and who will serve.

Balisage is about information as power. How you use it, well, that’s up to you.

### Saxon/C

Saturday, March 15th, 2014

Saxon/C by Michael Kay.

From the webpage:

Saxon/C is an alpha release of Saxon-HE on the C/C++ programming platform. APIs are offered currently to run XSLT 2.0 and XQuery 1.0 from C/C++ or PHP applications.

BTW, Micheal’s Why XSLT and XQuery? page reports that Saxon is passing more than 25,000 tests for XQuery 3.0.

If you are unfamiliar with either Saxon or Michael Kay, you need to change to a department that is using XML.

### Balisage 2014: Near the Belly of the Beast

• Design and implementation of XML vocabularies
• Case studies of the use of XML for publishing, interchange, or archving
• Alternatives to XML
• Expressive power and application adequacy of XSD, Relax NG, DTDs, Schematron, and other schema languages

Detailed Call for Participation: http://balisage.net/Call4Participation.html
Instructions for authors: http://balisage.net/authorinstructions.html

I checked, from the conference hotel you are anywhere from 25.6 to 27.9 miles by car from the NSA Visitor Center at Fort Meade.

Take appropriate security measures.

When I heard Balisage was going to be in Bethesda, the first song that came to mind was: Back in the U.S.S.R.. Followed quickly by Leonard Cohen’s Democracy Is Coming to the U.S.A..

I don’t know where the equivalent of St. Catherine Street of Montreal is in Bethesda. But when I find out, you will be the first to know!

Balisage is simply the best markup technology conference. (full stop) Start working on your manager now to get time to write a paper and to attend Balisage.

When the time comes for “big data” to make sense, markup will be there to answer the call. You should be too.

### xslt3testbed

Friday, January 3rd, 2014

xslt3testbed

From the post:

Testbed for trying out XSLT 3.0 (http://www.w3.org/TR/xslt-30/) techniques.

Since few people yet have much (or any) experience using XSLT 3.0 on more than toy examples, this is a public, medium-sized XSLT 3.0 project where people could try out new XSLT 3.0 features on the transformations to (X)HTML(5) and XSL-FO that are what we do most often and, along the way, maybe come up with new design patterns for doing transformations using the higher-order functions, partial function application, and other goodies that XSLT 3.0 gives us.

If you haven’t been investigating XSLT 3.0 (and related specifications) you need to take corrective action.

As an incentive, read Pearls Of XSLT And XPath 3.0 Design.

If you thought XSLT was useful for data operations, you will be amazed by XSLT 3.0!

### XSL TRANSFORMATIONS (XSLT) VERSION 3.0 [Last Call]

Friday, December 13th, 2013

XSL TRANSFORMATIONS (XSLT) VERSION 3.0

From the post:

The XSLT Working Group has published today a Last Call Working Draft of XSL Transformations (XSLT) Version 3.0. This specification defines the syntax and semantics of XSLT 3.0, a language for transforming XML documents into other XML documents. A transformation in the XSLT language is expressed in the form of a stylesheet, whose syntax is well-formed XML. Comments are welcome by 10 February 2014. Learn more about the Extensible Markup Language (XML) Activity.

One of the successful activities at the W3C.

A fundamental part of your XML toolkit.

### Frameless

Saturday, November 23rd, 2013

Frameless

From the webpage:

Frameless is an XSLT 2 processor running in the browser, directly written in JavaScript. It includes an XPath 2 query engine for simple, powerful querying. It works cross-browser, we have even reached compatibility with IE6 and Firefox 1.

With Frameless you’ll be able to do things the browsers won’t let you, such as using \$variables and adding custom functions to XPath. What’s more, XPath 2 introduces if/else and for-loops. We’ll even let you use some XPath 3 functionality! Combine data into a string using the brand new string concatenation operator.

Use way overdue math functions such as sin() and cos(), essential when generating data-powered SVG graphics. And use Frameless.select() to overcome the boundaries between XSLT and JavaScript.

When to use Frameless?

Frameless is created to simplify application development and is, due to its API, great for writing readable code.

It will make application development a lot easier and it’s a good fit for all CRUD applications and applications with tricky DOM manipulation.

Who will benefit by using it?

• Designers and managers will be able to read the code and even fix some bugs.
• Junior developers will get up to speed in no time and write code with a high level of abstraction, and they will be able to create prototypes that’ll be shippable.
• Senior developers will be able to create complicated webapplications for all browsers and write them declaratively

What it’s not

Frameless doesn’t intend to fully replace functional DOM manipulation libraries like jQuery. If you like you can use such libraries and Frameless at the same time.

Frameless doesn’t provide a solution for cross-browser differences in external CSS stylesheets. We add prefixes to some inline style attributes, but you should not write your styles inline only for this purpose. We do not intend to replace any CSS extension language, such as for example Sass.

Frameless is very sparse on documentation but clearly the potential for browser-based applications is growing.

I first saw this in a tweet by Michael Kay.

### X* 3.0 Proposed Recommendations

Tuesday, October 22nd, 2013

XQuery 3.0, XPath 3.0, Data Model, Functions and Operators and XSLT and XQuery Serialization 3.0

From the post:

The XML Query Working Group and the XSLT Working Group have published five Proposed Recommendations today:

What’s today? October 22nd?

You almost have 30 days. 😉

Which one or more are you going to read?

I first saw this in a tweet by Jonathan Robie.

### N1QL – It Makes Cents! [Rediscovery of Paths]

Friday, October 11th, 2013

N1QL – It Makes Cents! by Robin Johnson.

*Ba Dum Tschhh* …See what I did there? Makes cents? Get it? Haha.

So… N1QL (pronounced Nickel)… Couchbase’s new next-generation query language; what is it? Well, it’s a rather genius designed, human readable / writable, extensible language designed for ad-hoc and operational querying within Couchbase. For those already familiar with querying within Couchbase, that blurb will probably make sense to you. If not – well, probably not, so let me clear it up a little more.

But before I do that, I must inform you that this blog article isn’t the best place for you to go if you want to dive in and get started learning N1QL. It is a view into N1QL from a developer’s perspective including why I am so excited about it, and the features I am proud to point out. If you want to get started learning about N1QL, click here. Or alternatively, go and have a go of the Online Tutorial. Anyway, back to clearing up what I mean when I say N1QL…

“N1QL is similar to the standard SQL language for relational databases, but also includes additional features; which are suited for document-oriented databases.” N1QL has been designed as an intuitive Query Language for use on databases structured around Documents instead of tables. To locate and utilise information in a document-oriented database, you need the correct logic and expressions for navigating documents and document structures. N1QL provides a clear, easy-to-understand abstraction layer to query and retrieve information in your document-database.

Before we move on with N1QL, let’s talk quickly about document modeling within Couchbase. As you probably know; within Couchbase we model our documents primarily in JSON. We’re all familiar with JSON, so I won’t go into it in detail, but one thing we need to bear in mind is the fact that: our JSON documents can have complex nested data structures, nested arrays and objects which ordinarily would make querying a problem. Contrary to SQL though, N1QL has the ability to navigate nested data because it supports the concept of paths. This is very cool. We can use paths by using a dot-notation syntax to give us the logical location of an attribute within a document. For example; if we had an e-commerce site with documents containing customers’ orders, we could look inside those documents, to an Nth nested level for attributes. So if we wanted to look for the customer’s shipping street: (emphasis in original)

Paths are “very cool,” but I thought that documents could already be navigated by paths?

Yes?

True, CouchDB uses JSON documents but the notion of paths in data structures isn’t news.

Not having paths into data structures, now, that would be news. 😉

### Four and Twenty < / > ! Baked in a Pie…

Tuesday, May 28th, 2013

Balisage 2013 program is online!

From Tommie Usdin’s email:

Balisage is an annual conference devoted to the theory and practice of descriptive markup and related technologies for structuring and managing information. Participants typically include XML users, librarians, archivists, computer scientists, XSLT and XQuery programmers, implementers of XSLT and XQuery engines and other markup-related software, Topic-Map enthusiasts, semantic-Web evangelists, members of the working groups which define the specifications, academics, industrial researchers, representatives of governmental bodies and NGOs, industrial developers, practitioners, consultants, and the world’s greatest concentration of markup theorists. Discussion is open, candid, and unashamedly technical.

Major features of this year’s program include several challenges to the fundamental infrastructure of XML; case studies from government, academia, and publishing; approaches to overlapping data structures; discussions of XML’s political fortunes; and technical papers on XML, XForms, XQuery, REST, XSLT, RDF, XSL-FO, XSD, the DOM, JSON, and XPath.

Attending Balisage even once will keep you from repeating mistakes in language design.

Attending Balisage twice will mark you as a markup expert.

Attending Balisage three or more times, well, this is an open channel so we can’t go there.

But you should go to Balisage!

Send your pics from Saint Catherine Street!

### XMLQuire Web Edition

Sunday, March 17th, 2013

XMLQuire Web Edition: A Free XSLT 2.0 Editor for the Web

From the webpage:

XSLT 2.0 processing within the browser is now a reality with the introduction of the open source Saxon-CE from Saxonica. This processor runs as a JavaScript app and supports JavaScript interoperability and user-event handling for the era of HTML5 and the dynamic web.

This Windows product, XMLQuire, is an XSLT edtior specially extended to integrate with Saxon-CE and support the Saxon-CE language extensions that make interactive XSLT possible. Saxon-CE is not included with this product, but is available from Saxonica here.

*nix folks will have to install Windows 7 or 8 on a VM to take advantage of this software.

Worth the effort if for no other reason than to see how the market majority lives. 😉

I first saw this in a tweet by Michael Kay.

### Lux

Saturday, March 16th, 2013

Lux

Lux is an open source XML search engine formed by fusing two excellent technologies: the Apache Lucene/Solr search index and the Saxon XQuery/XSLT processor.

At its core, Lux provides XML-aware indexing, an XQuery 1.0 optimizer that rewrites queries to use the indexes, and a function library for interacting with Lucene via XQuery. These capabilities are tightly integrated with Solr, and leverage its application framework in order to deliver a REST service and application server.

The REST service is accessible to applications written in almost any language, but it will be especially convenient for developers already using Solr, for whom Lux operates as a Solr plugin that provides query services using the same REST APIs as other Solr search plugins, but using a different query language (XQuery). XML documents may be inserted (and updated) using standard Solr REST calls: XML-aware indexing is triggered by the presence of an XML-aware field in a document. This means that existing application frameworks written in many different languages are positioned to use Lux as a drop-in capability for indexing and querying semi-structured content.

The application server is a great way to get started with Lux: it provides the ability to write a complete application in XQuery and XSLT with data storage backed by Lucene.

If you are looking for experience with XQuery and Lucene/Solr, look no further!

May be a good excuse for me to look at defining equivalence statements using XQuery.

I first saw this in a tweet by Michael Kay.

### “…XML User Interfaces” As in Using XML?

Tuesday, February 19th, 2013

International Symposium on Native XML user interfaces

This came across the wire this morning and I need your help interpreting it.

Why would you want to have an interface to XML?

All these years I have been writing XML in Emacs because XML wasn’t supposed to have an interface.

Brave hearts, male, female and unknown, struggling with issues too obscure for mere mortals.

Now I find that isn’t supposed to be so? You can imagine my reaction.

I moved my laptop a bit closer to the peat fire to make sure I read it properly. Waiting for the ox cart later this week to take my complaint to the local bishop about this disturbing innovation.

😉

15 March 2013 — Peer review applications due
19 April 2013 — Paper submissions due
19 April 2013 — Applications due for student support awards due
21 May 2013 — Speakers notified
12 July 2013 — Final papers due
5 August 2013 — International Symposium on Native XML user interfaces
6–9 August 2013 — Balisage: The Markup Conference

International Symposium on
Native XML user interfaces

Monday August 5, 2013 Hotel Europa, Montréal, Canada

XML is everywhere. It is created, gathered, manipulated, queried, browsed, read, and modified. XML systems need user interfaces to do all of these things. How can we make user interfaces for XML that are powerful, simple to use, quick to develop, and easy to maintain?

How are we building user interfaces today? How can we build them tomorrow? Are we using XML to drive our user interfaces? How?

This one-day symposium is devoted to the theory and practice of user interfaces for XML: the current state of implementations, practical case studies, challenges for users, and the outlook for the future development of the technology.

Relevant topics include:

• Editors customized for specific purposes or users
• User interfaces for creation, management, and use of XML documents
• Uses of XForms
• Making tools for creation of XML textual documents
• Using general-purpose user-interface libraries to build XML interfaces
• Looking at XML, especially looking at masses of XML documents
• XML, XSLT, and XQuery in the browser
• Specialized user interfaces for specialized tasks
• XML vocabularies for user-interface specification

Presentations can take a variety of forms, including technical papers, case studies, and tool demonstrations (technical overviews, not product pitches).

This is the same conference I wrote about in: Markup Olympics (Balisage) [No Drug Testing].

In times of lean funding for conferences, if you go to a conference this year, it really should be Balisage.

You will be the envy of your co-workers and have tales to tell your grandchildren.

Not bad for one conference registration fee.

### Markup Olympics (Balisage) [No Drug Testing]

Thursday, January 10th, 2013

Markup athletes take heart! Unlike venues that intrude into the personal lives of competitors, there are no, repeat no drug tests for presenters at Balisage!

Fear no trainer betrayals or years of being dogged by second-raters in the press.

Eat, drink, visit, ???, present, in the company of your peers.

The more traditional call for participation, yawn, has the following details:

Dates:

15 March 2013 – Peer review applications due
19 April 2013 – Paper submissions due
19 April 2013 – Applications due for student support awards due
21 May 2013 – Speakers notified
12 July 2013 – Final papers due

5 August 2013 – Pre-conference Symposium on XForms
6-9 August 2013 – Balisage: The Markup Conference

From the call:

Balisage is where people interested in descriptive markup meet each year in August for informed technical discussion, occasionally impassioned debate, good coffee, and the incomparable ambience of one of North America’s greatest cities, Montreal. We welcome anyone interested in discussing the use of descriptive markup to build strong, lasting information systems.

Practitioner or theorist, tool-builder or tool-user, student or lecturer — you are invited to submit a paper proposal for Balisage 2013. As always, papers at Balisage can address any aspect of the use of markup and markup languages to represent information and build information systems. Possible topics include but are not limited to:

• XML and related technologies
• Non-XML markup languages
• Big Data and XML
• Implementation experience with XML parsing, XSLT processors, XQuery processors, XML databases, XProc integrations, or any markup-related technology
• Semantics, overlap, and other complex fundamental issues for markup languages
• Case studies of markup design and deployment
• Quality of information in markup systems
• JSON and XML
• Efficiency of Markup Software
• Markup systems in and for the mobile web
• The future of XML and of descriptive markup in general
• Interesting applications of markup

In addition, please consider becoming a Peer Reviewer. Reviewers play a critical role towards the success of Balisage. They review blind submissions — on topics that interest them — for technical merit, interest, and applicability. Your comments and recommendations can assist the Conference Committee in creating the program for Balisage 2013!

How:

More IQ per square foot than any other conference you will attend in 2013!

### Balisage 2013 – Dates/Location

Tuesday, November 20th, 2012

Tommie Usdin just posted email with the Balisage 2013 dates and location:

Montreal, Hotel Europa, August 5 – 9 , 2013

Hope that works with everything else.

That’s the entire email so I don’t know what was meant by:

Hope that works with everything else.

Short of it being your own funeral, open-heart surgery or giving birth (to your first child), I am not sure what “everything else” there could be?

You get a temporary excuse for the second two cases and a permanent excuse for the first one.

Now’s a good time to hint about plane fare plus hotel and expenses for Balisage as a stocking stuffer.

And to wish a happy holiday Tommie Usdin and to all the folks at Mulberry Technology who make Balisage possible all of us. Each and every one.

### Destination: Montreal!

Tuesday, May 29th, 2012

If you remember the Saturday afternoon sci-fi movies, Destination: …., then you will appreciate the title for this post. 😉

Tommie Usdin and company just posted: Balisage 2012 Call for Late-breaking News, written in torn bodice style:

The peer-reviewed part of the Balisage 2012 program has been scheduled (and will be announced in a few days). A few slots on the Balisage program have been reserved for presentation of “Late-breaking” material.

Proposals for late-breaking slots must be received by June 15, 2012. Selection of late-breaking proposals will be made by the Balisage conference committee, instead of being made in the course of the regular peer-review process.

If you have a presentation that should be part of Balisage, please send a proposal message as plain-text email to info@balisage.net.

In order to be considered for inclusion in the final program, your proposal message must supply the following information:

• The name(s) and affiliations of all author(s)/speaker(s)
• The email address of the presenter
• The title of the presentation
• An abstract of 100-150 words, suitable for immediate distribution
• Disclosure of when and where, if some part of this material has already been presented or published
• An indication as to whether the presenter is comfortable giving a conference presentation and answering questions in English about the material to be presented
• Your assurance that all authors are willing and able to sign the Balisage Non-exclusive Publication Agreement (http://www.balisage.net/BalisagePublicationAgreement.pdf) with respect to the proposed presentation

In order to be in serious contention for inclusion in the final program, your proposal should probably be either a) really late-breaking (it happened in the last month or two) or b) a paper, an extended paper proposal, or a very long abstract with references. Late-breaking slots are few and the competition is fiercer than for peer-reviewed papers. The more we know about your proposal, the better we can appreciate the quality of your submission.

Please feel encouraged to provide any other information that could aid the conference committee as it considers your proposal, such as a detailed outline, samples, code, and/or graphics. We expect to receive far more proposals than we can accept, so it’s important that you send enough information to make your proposal convincing and exciting. (This material may be attached to the email message, if appropriate.)

The conference committee reserves the right to make editorial changes in your abstract and/or title for the conference program and publicity. (emphasis added to last sentence)

The conference committee reserves the right to make editorial changes in your abstract and/or title for the conference program and publicity.

The conference committee might change your abstract and/or title to say something …. controversial? ….attention getting? ….CNN / Slashdot worthy?

Bring it on!

Submit late breaking proposals!

### Would You Know “Good” XML If It Bit You?

Tuesday, February 14th, 2012

XML is a pale imitation of a markup language. It has resulted in real horrors across the markup landscape. After years in its service, I don’t have much hope of that changing.

But, the Princess of the Northern Marches has organized a war council to consider how to stem the tide of bad XML. Despite my personal misgivings, I wish them well and invite you to participate as you see fit.

Oh, and I found this message about the council meeting:

International Symposium on Quality Assurance and Quality Control in XML

Monday August 6, 2012

Paper submissions due April 20, 2012.

A one-day discussion of issues relating to Quality Control and Quality Assurance in the XML environment.

XML systems and software are complex and constantly changing. XML documents are highly varied, may be large or small, and often have complex life-cycles. In this challenging environment quality is difficult to define, measure, or control, yet the justifications for using XML often include promises or implications relating to quality.

We invite papers on all aspects of quality with respect to XML systems, including but not limited to:

• Defining, measuring, testing, improving, and documenting quality
• Quality in documents, document models, software, transformations, or queries
• Case studies in the control of quality in an XML environment
• Theoretical or practical approaches to measuring quality in XML
• Does the presence of XML, XML schemas, and XML tools make quality checking easier, harder, or even different from other computing environments
• Should XML transforms and schemas be QAed as software? Or configuration files? Or documents? Does it matter?

Paper submissions due April 20, 2012.

Details at: http://www.balisage.net/QA-QC/

You do have to understand the semantics of even imitation markup languages before mapping them with more robust languages. Enjoy!

• REST for document resource nodes
• tagging journal article supplemental materials
• using 15 year old SGML documents in current software

and then goes on to talk about why markup geeks should be at Balisage.

I’ll make that shorter:

If you see either < or > at work or anyone talks about them, you need to be at Balisage 2011.

If you are not a markup geek, you will be one by the time you leave. Road to Damascus sort of experience. Or you will decide to move to San Francisco. Either way, what do you have to lose?

### Practical Transformation Using XSLT and XPath

Sunday, February 13th, 2011

A new edition of Practical Transformation Using XSLT and XPath by Ken Holman is out.

While not topic map specific, ;-), this is one of the two resources you need for transformations getting to (or from) topic maps using XSLT and XPath. The other one, would be: XSLT 2.0 and XPath 2.0: programmer’s reference. (You can also use both of these for non-topic map, XML based work.)

While your looking at Ken’s training resources, note his series on UBL (Universal Business Language).

I mention that because the greater the exposure of business systems the greater the need for the mapping of semantics (that means topic maps).
